Thats pretty cool! If you like that the C.A.D software company Autodesk have developed a similar piece of software that you can get for free as desktop or mobile app called '123d Catch'

You take a series of photos from different angles of something, similar to attempting to create a photomerge in photoshop, and the software automatically works out the geometry from the perspective and creates a 3d mesh of the object. I've tried it out, the mesh is never perfect, but its a nice bit of fun and useful as your never going to be carrying a full on laser scanner around!

No it isn't. And they are two pieces of software for two very different purposes/tasks. There are better alternatives to Catch (testing some at the moment) but your comparison and recommendation is just silly.

Oh don't get me wrong the actual '123d' design or create pieces of software are awful! I'm a Rhino and 3d Studio Max man myself due to my background in Architecture.

The reason I mentioned '123d catch' though is that it automatically creates models from photographs like the software in the original submission and is actually relatively good at what it does for what it is, worth checking out even if you hate the other pieces of software in the '123d' line up.
